42AI comes out of stealth with $62.5M and a behavioral model

Israeli startup 42AI has officially emerged from stealth mode after three years of development, securing $62.5 million in seed funding. The company is currently deploying its predictive system at a select group of financial brokerages, where the model is utilized to help forecast how individual traders will react to volatile market conditions.

The system is designed to uncover people's internal motivations rather than merely extrapolating patterns based on their historical actions. To achieve this, 42AI analyzes how individuals respond to seemingly unrelated events, such as completing KYC verifications, onboarding procedures, customer support calls, money transfers, or executing stock trades.

The startup converts these behavioral observations into mathematical representations of individual traits, which are subsequently fed into a transformer-based world model outlining decision probabilities under various circumstances. Additionally, a separate language model generates textual explanations for its predictions. Over three years, the company combined psychological research with neuroscience, genetics, and insights from expert advisors alongside Dan Shechtman, the 2011 Nobel Prize laureate in Chemistry.

Regarding market performance, 42AI claims its model achieves a 98% accuracy rate, measured primarily by whether trading flows fall within the predicted range. The model also consistently achieves an F1 score between 0.8 and 0.85 for forecasting trading direction and volume. Clients compensate the startup through flat fees or a percentage of generated value, with one brokerage reportedly generating roughly $30 million in additional value via dynamic hedging.
